Power components of electric locomotive

The invention relates to the technical field of an electric locomotive, in particular to a power component of an electric locomotive.

At present, electric locomotive mainly uses a motor as a power source, which is transmitted to the wheels through a transmission device to drive the vehicle forward. In order to increase the torque or reduce the speed of the motor, the motor is usually combined with the transmission of the reduction gear set. Based on the workload, working speed, and the need to maintain the motor's operation at optimal working efficiency, the motor and the reduction gear set must be properly matched to obtain better operating characteristics. In addition, the motor needs to be equipped with an appropriate controller (device). The controller (device) is used to detect the output speed of the motor and transmit a control signal to control the speed of the motor in real time.

Traditionally, the motor, the reduction gear set and the controller are independent components or devices, so the total volume of each component or device is large. The electric locomotive needs to have a large installation space for each component or device to be smooth. Installation and positioning.

In addition, each component or device needs to be connected by wires (wires) for detection and control. However, the independent components and devices expose the wires, which in turn causes the wires to interfere significantly with the installation behavior.

The invention aims to solve the shortcomings that the power components of the traditional electric locomotive are too large and the wires are obviously exposed.

An object of the present invention is to provide a power component of an electric locomotive, which is capable of integrating an electric motor, driven teeth, and control elements in the same body, thereby forming a three-in-one unit to reduce the volume, and enabling the wire to be integrated in the body To reduce interference during installation.

In order to achieve the above-mentioned object and effect, the power module disclosed in the present invention includes a body including a base, and the interior of the base has a partition layer. One side of the partition layer is a first set of space, and the other side A second set of space is provided; an electric motor is attached to the body, the electric motor has an output shaft, the output shaft is combined with a transmission gear, the transmission gear is located in the first set of space; a driven gear Installed in the body, a gear shaft is installed in the axial direction of the driven gear, the driven gear is located in the first group space and meshes with the transmission gear, and one end of the gear shaft penetrates the body; and a control element It is installed in the second group of distribution spaces and is electrically connected to the electric motor.

In this way, the electric motor, the transmission gear, and the control element are installed in the body to form a three-machine integrated form, so the overall volume can be significantly reduced. In addition, the control element is electrically connected to the electric motor, so the control element and the electric motor are installed in the same body, and the wires connecting the control element and the electric motor can be used to be integrated inside the body, reducing the The wire interferes with the assembly line of the power module.

Please refer to FIG. 1, which shows an embodiment of the present invention. An electric motor 40, a driven gear 50, and a control element (not shown) are installed inside a body 10 to form a three-machine unit.

Please refer to FIGS. 2 and 3. The body 10 of this embodiment includes a base 20. The base 20 has a partition layer 22 therein. One side of the partition layer 22 is a first group of matching spaces 24, and the other side is a second group of matching spaces 26. The first matching space 24 has a first gear chamber 28 communicating with a second gear chamber 30. Second, the first gear chamber 28 has a first shaft hole 32 therethrough, and the second gear chamber 30 has a second shaft hole 34 therethrough.

Referring to FIGS. 2 and 4, the electric motor 40 disclosed in this embodiment has a power output shaft 42, and one end of the power output shaft 42 is coupled with a transmission gear 44. The electric motor 40 is installed in the body 10. In particular, the transmission gear 44 is located in the first gear chamber 28 of the first grouping space 24 of the base 20. One end of the output shaft 42 passes through the first shaft hole 32.

The driven gear 50 disclosed in this embodiment is axially mounted with a gear shaft 52. The driven gear 50 is located in the second gear chamber 30 of the first grouping space 24 and meshes with the transmission gear 44. In addition, one end of the gear shaft 52 passes through the second shaft hole 34, so that the gear shaft 52 passes through. The bottom of the base 20, that is, one end of the gear shaft 52 penetrates the body 10.

Please refer to FIG. 2, FIG. 4 and FIG. 5. In addition to the base 20, the body 10 disclosed in this embodiment further includes a connecting base 60. The connecting base 60 is assembled on one side of the base 20 and corresponds to the first grouping space. twenty four. The connecting base 60 has a through hole 62. One end of the electric motor 40 passes through the through hole 62 of the connecting base 60. Furthermore, a casing cover 70 is mounted on the connecting base 60 and used to close the through hole 62, so that one end of the electric motor 50 is accommodated in the casing cover 70.
